This option exists to facilitate the use of template meta-programming techniques to select, based on this enumeration, which auto-differentiable number type will be used to perform calculations. It will not permit any computations because the underlying number types resulting from its selection are floating point types, rather than auto-differentiable numbers.

adolc_taped

Taped forward and reverse-mode ADOL-C number type (n-differentiable).

First derivatives will be computed using reverse mode, while the second derivatives will be computed using forward mode. Even higher-order derivatives can be computed using ADOL-C's own driver functions.
